應用示例:https://github.com/Hi-Fi/writetable-example-with-grails保存失敗,JSON交Grails中
在示例應用中,控制器通過GSP的頁面使用或與CURL張貼形式時很好地工作。命令的捲曲:
curl "http://localhost:8080/junk/team/save" --data "name=team&players"%"5B0"%"5D.firstName=first&players"%"5B0"%"5D.lastName=last&players"%"5B0"%"5D.position=position&create=Create" --compressed.
的問題是與使用JSON,這產生相同的(根據轉儲())對象相同的請求,但無法保存嵌套值。
在作出下列與SOAPUI(本地主機:8080 /垃圾/ API/REST):POST
{
name: "Team name",
players: [
{
firstName: "Player first name",
lastName: "Player last name",
position: "Player position"
}
]
}
我只是得到錯誤:
| Error 2014-12-20 21:02:47,050 [http-bio-8080-exec-1] ERROR hibernate.AssertionFailure - an assertion failure occured
(this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)
Message: null id in junk.Player entry (don't flush the Session after an exception occurs)

父對象(隊)仍然保存甚至有這個錯誤。隨着Hibernate4整個保存失敗,所以更新到它沒有幫助。解決這一明確「團隊」,每個「播放器」之類
team.players.each {it.team = team}
